Beitknotvn that I, SAMUEL V. Gimariiioir,

a citizen of the-United States; residing at Paradox in the. county otjMontrose and State of Colorado, have invented certain. new and useful Improvenients'in Shock-Ah I sci-her Attachmentaoif which the following is a specification. 1.

This invention relates tov improveinentr-s:in

shock absorber attachments.

An important objectlozl this invention toprovicle ashock absorber attachment having novel means whereby the spring of the shock absorber may be reacllly anclcon;

veni'ently compressedpreparatory to applying or removing the shock absorber.

' Aturther object-of the invention forming the subject-matter of this application .isto provide a shock absorber attachment having a spring compressing i plate aclaptecluto be arranged at the baseof the spring and prothe spr ng videclovvith' novel means'to secure in position. i i

The inventio'nfltorming the subj cot-matter ofthis application aims also to provide in a shock absorber attachment reliable and casily operatedmeans whereby the lever oi the shock absorber may be held in a retracted position While the cushioning spring is. re

moved.

A further object ofthe invention is to' provide a shock absorber attachment which may be conveniently applied to the shock.

absorbers now in use, Without in any Way altering the construction of the same.

A further objeotf-of the inventio-nis to provi clef aushockabsorber attachment which is desirable inauseyot highly simplified construction and cheap tomanuiacture. i the 111-,

The vehicle here in illustrated i is provided with shock absorbers generally itlesignated by theinurneral 18 and which comprise levers, 19 -connectecl;

The other end portion "of elongated spring compression plate 36. g p is provided with pair of upstanding lugs 39 which are adaptedto engage the-dinner sides of thelowermost convolution of the "helical. spring so as to cooperate with the upsta ndingend 38" in securing the. spring" 7 against movement. The end ofthe spring compression plate'36 having the lugs .39 is tapered, rounded and curved somewhatiso that upon the applicationot the spring 38 the elongated-plate 36 may be forced'in'to :posi i tion between the semi-circular upstanding flanges 35. The elongated spring compress1on-plate36 1s provided-mtermediate its ends with a bolt-receiving opening 40 and' with diametrically opposed slots ll .which 43 may be extended through "the g plate as.

/ The rear lugl8 is provided'with a transverse notch 50 which prevents-the lug from riding M t up above "the convolution "at the upper" end of the spring; V The upper spring compress ingplate 46 of elongated formation is "adapted-topics arranged within the slot-24 of the'lever 19. and isflprovided with'an openin g52"forthereception of the 'bo'lt 43. The plate 46 also has opposed slots 53 which allow. the pin42 carried bythe bolt 43 to be passed' through thefplate when assembling M "the shock absorber The bolt 48 has threaded e'n'gagement with a sleeve nut 56 whi ch rotatably extends through i the opening 52 in the plate 46. "An annular enlargement. or"

shoulder 58 formed on the sleevenut 56 ad i jacent the rear'end'o'f the same bearsagainstthe outerfface' of the plate 46 and-when rotated serves tomove-the plate lfifin-the 'di-f ffrection of theplate 36 and thereby com- I press/the helical springtf It will beob-- served that the sleeve nutv 56 extends" for aj considerable distance into the helical spr ng and serves a s e means for spacing the side wall-o f opening 52 from the threads. of the bolt 13 whereby-said threads areprevented from becoming mutilated as theresult of movement of the plate lfirwitli relation to the bolt. 'It'win be noted by reft-e'rence particularly to Figures 3 and 5 that the nut 56 is only threaded at its lower end to substantiallyonethird of its length and that the rest cit-the nut is smooth bored forming" a sleeve fortherbolt. By this arran ement, a very short bolt maybe used and this has the advantage thatthe over all length of the tool-will also be'shorter so that,

for this reason, it will be'easier to remove than if the tool. had a short nut with a long boltextending considerably above the shock absorber. The rear portionott the sleeve nut 56 is polygonal sided asmdicat'ed' at 66 so as to provide meanswhereby a wrench may tightening or loosening the same.

be engaged with the nutfor the purpose of ne of'the major difiiculties present in connection withthe use oi the shock labsorbers hereinillustrated is thefact that it is:

extremely diflicult and involves'much labor to apply or remove the coiled spr1ngs',"s1nce it is necessary under 'ordinaryconditions to remove. the pivot elementsQO, 22 and'asso-v ciated'pa'rts. Withthe use ofthis' attachment it is merely necessary to'compress the coiled spring preparatory to applying or re moving the same by tightening up on the sleeve nutp'5f8; 'ln -thus .tighteningup onthe sleeve nut, the plates 36 and 46 are drawn to-:

gether so that thespring is: compressed and may when compressed. be readily.removed.-

Preparatory to removing the. coiled spring the lever is engaged by 3 a flexible element 66 able'means to alever 68. The lever 68 may be extended over the adjacent wheel-and swung downwardly so as to retain theilever 19 of the shock absorber in aretractedposh tion. The rear end of the lever 68=may upon being swung downwardly be anchored to the which is detachably connected by anyflsuit wheel by" m'eanslor" a flexible element in the form of-a cha'in'TO; Uponllocking the lever 19 in a retracted position andafter the com pression ofthe helical spring,the latter may be readily and conveniently detached for the purpose of replacement or for any-other j purpose. I d i a i i U v 'V hth referenceito the'foregoing description, ta'ken in' connection with the accom--l H panying drawings, it will bea a pparent that the" attachment forming the su-bject matter of tlllS; application may-be readily and 0011- veniently applied to a shock absorber with out in anyway altering the construction of i the vehicleorthe-shockabsorber.

-When applied the attachment does not in} terfere with the shock absorbing jqualitiesof; the spring or does in any waylinterfere -with the operation. ofjthewshock}absorber;' In fact the attachmentfgreatly strengthens;

and increases the utility of the shock absorber.

It is to be understood that the form of the invention herewith shown anddescribed is to be taken as a preferred example of the same and that such minor changes in arrangement and construction of parts may be made as will remain Within the spirit of the inven tion and the scope of What is claimed.

Having thus described the invention, What is claimed as new is;

1 In an attachment for shock absorbers,

the combination with an oblong base plate provided at one end With an upstanding flange and near its opposite endvvith lugs rising "from the side edges oi the plate, said flange and said lugs adapted to engage-respectively with the exterior and interior peripheries of a coil at one end of a spring, a bolt detachably connected to said plate, a

second plate loosely mounted on the bolt and provided at one end with depending spaced, lugs adapted to embrace a coil at the other endof said spring, and a nut threaded end or said spring, said seat and said lever having elongated apertures running at right angles to the axis of the spring; said assembling attachment comprising a pair of plates; a screw and a nut having engagement respectively with one or": each of said plates, one of said plates fitting inthe aperture of seat and being provided with inner and outer coil engaging elements at its opposite ends including an upstanding flange and depending lugs; the other of said plates fitting in the aperture 01" said lever and provided with fingers gripping around a coil.

In testimony whereof I afiix my signature;
